We continue our conversation with Dave Zirin, author of the book "Brazil's Dance with the Devil: The World Cup, the Olympics, and the Fight for Democracy," and Jules Boykoff, author of "Power Games: A Political History of the Olympics."

This comes as Brazil is battling an economic recession, a massive Zika outbreak and its worst political crisis in over two decades.
